Drilling fluid contributes more than 40% of total cost of oil well drilling. There are more than 2’000 drilling additives used in drilling of oil and gas wells, most of them are costly and not available locally. The objective of this paper is to use Pomegranate Juice as drilling fluid additive for filtration lost controlling and it is a good choice for replacement the indecomposable mud additives and saving the see and land areas near the crude oil exploitation installations. To achieve this objective the rheology of mud in which this processed seeds is added as an additive is experimentally investigated. Physical properties of the fluid such as viscosity, mud weight, gel strength and filtration property. The result of the research is expected to be used in Iranian oil/gas drilling industry.
